Sun packaged up a version of the collections classes for JDK1.1, which
you can find with a little searching on their site. It's working well
for me.
The main difference between the 1.1 and 1.2 flavor of the collections,
as I understand it, is that the 1.2 collections are part of the core and
the 1.1 collections live in a strange and different package,
com.sun.java.util.collections . Reason is that some SecurityManagers,
such as those found in most browsers, balk at loading non-core classes
named to look like core classes.
So if you're working in an environment where the security thing might be
a concern -- say, you're building applets and including the collections
classes in the jarfile -- you'll have to use the 1.1 versions and change
a few "import" statements when you finally move to 1.2. If that's not a
concern, I suspect that you're right -- the 1.2 collections code
probably works in a 1.1 environment.
